AAO membranes were purchased from Whatman (Anodisc 6809-6012, 25 mm diameter, 100 nm pore size) and rendered electrically conductive by depositing 100-nm Au on one side of the membrane via thermal evaporation. The electrolytes were prepared by dissolving the corresponding salts zinc bis(trifluoromethanesulfonyl)imide (Alfa Aesar), lithium bis(trifluoromethanesulfonyl)imide (Solvay), and/or tetrabutylammonium hexafluorophosphate (Sigma-Aldrich) in PC (anhydrous, 99.7%, Sigma-Aldrich), EG (anhydrous, 99.8%, Sigma-Aldrich), and/or dimethyl sulfoxide (Sigma-Aldrich). PC and EG were dried over molecular sieves (4 Å, Sigma-Aldrich) before use. Ferrocene and anthraquinone were purchased from Sigma-Aldrich.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
